2. Application areas

Architecture: roofs, walls, curtain walls (such as airports and gymnasiums).

Home appliances: refrigerator panels, air conditioner shells, oven liner.

Transportation: compartment partitions, container shells.

Furniture: office partitions, cabinet door panels.

3. Differences from PPGI and PPGL

Type Substrate Features Main uses

PPGI Galvanized sheet (GI) Low cost, weak corrosion resistance Ordinary buildings, home appliances

PPGL Alu-zinc (GL) Excellent corrosion resistance/heat resistance, long life High-end buildings, industrial environments

PPAL Aluminum-coated sheet (AL) High temperature resistance (up to 650°C), good reflectivity Chimneys, ovens

4. Purchase considerations

Coating type: PVDF for outdoor use, polyester for indoor use.

Coating weight: ≥90g/m² is recommended for coastal/industrial areas.

Environmental protection standards: Confirm that there is no chromium treatment (RoHS compliant).

Surface texture: Embossing, matte and other processes affect the appearance and stain resistance.

PPGI has dual protection through substrate + coating, combining functionality and aesthetics, and is an ideal material to replace traditional spraying
